以迟熟超级杂交中稻Y两优087为材料,于2013—2015年在同一地点连续作中稻适时早播,通过对其叶龄和分蘖动态等进行系统的苗情观测,掌握了该品种与季节同步的有效分蘖临界叶龄期、高峰苗期、穗轴分化期、枝梗分化期、拔节期和颖花分化期、花粉母细胞形成与减数分裂期和抽穗结实期等8个关键叶龄期及其群体发育特征,介绍了其精确定量栽培技术。
Yishougyou 087, a late-maturing middle-season hybrid rice, was used to sow early sowing of Nakao at the same site in 2013-2015. Soybean and its tillering dynamics were systematically observed by seedling observation. Eight key leaf ages, including effective critical tillering age, peak seedling stage, cotyledon differentiation stage, branch stem differentiation stage, jointing stage and spikelet differentiation stage, pollen mother cell formation and meiosis stage and heading stage, Period and its population development characteristics, introduced its precise quantitative cultivation techniques.
